Convulsions and respiratory arrest in association with desmopressin administration for the treatment of a bleeding tonsil in a child with borderline haemophilia.

Desmopressin (DDAVP) may be used to augment the action of factor VIII in mild haemophilia. Its use has been associated with serious adverse effects. We report a case of a three-year-old child with a family history of haemophilia who suffered complications due to severe acute hyponatraemia following the administration of this drug for post-tonsillectomy bleeding.
